phone numbers are usually associated with new card

Using a blank SIM card generally means that a user is given a digital clean slate. Since there is no information on a blank SIM card, users have to re-enter contacts and other associated cell phone account details onto the SIM card. Different phone numbers are usually associated with the new cards.

Blank SIM cards are typically inexpensive. They usually accompany new cell phones to aid in the proper activation of a new phone line. However, a new phone line is not required to obtain a blank SIM card. They may be easily purchased from cell phone company websites.
